Swollen elastomer liquid crystals undergo significant deformations by application of an electric field perpendicular to their alignment axis, as shown in experiments by Urayama et al. [Urayama K, Honda S, Takigawa T (2006) Macromolecules 39:1943-1949]. Here we clarify this surprising effect at the molecular level using large-scale Monte Carlo simulations of an off-lattice model based on a soft Gay-Berne potential. We provide the internal change of molecular organization, as well as the key observables during the actuation cycle.
肿胀弹性体液晶通过施加垂直于其取向轴的电场会发生显著变形，这在 Urayama 等人的实验中得到了证实。[Urayama K, Honda S, Takigawa T (2006) Macromolecules 39:1943-1949]。在这里，我们使用基于软 Gay-Berne 势的无格子模型的大规模蒙特卡罗模拟，在分子水平上澄清了这一令人惊讶的效应。我们提供了分子组织的内部变化，以及在致动循环期间的关键可观察量。
